Development and Utilization of a Patient-Oriented Outpatient Guidance System / 대한의료정보학회지

OBJECTIVES: To develop a tool which can easily access the hospital information system (HIS) to facilitate outpatient care and maximize patient satisfaction on his or her hospital visit. METHODS: Our Center for Informatics developed an outpatient guidance system (OGS) after careful analysis of the list of daily tasks undergone by patients and related work processes. Bluetooth beacons were installed to assist patients, to inform them of points of interest, and to guide them along the proper routes to and within the hospital. RESULTS: The OGS conveniently provided patients' clinic schedules, routes to the hospital, and direct costs; all of this information was embedded in the HIS accessed from patients' personal mobile devices or kiosks. Patients were also able to identify their locations within the hospital, receiving proper directions to subsequent task. Since its launch in October 2014, the number of mobile accesses increased from 4,011 to 8,242 per month within a year. CONCLUSIONS: The substantial growth of interest in and use of our OGS in such a short period indicate that this system has been successfully incorporated into patients' daily activities. We believe that this system will continue to help improve health services and the well-being of those visiting the hospital.

A Comparative Study of the Diagnostic Performance of the GENEDIA Avellino Corneal Dystrophy Mutation Detection Kit and Screening Master Mix and a Direct Sequencing Method to Detect Mutations in the TGFB1 Gene / 임상검사와정도관리

BACKGROUND: Mutations in the gene encoding transforming growth factor-beta induced (TGFBI) are associated with corneal dystrophies. We evaluated the diagnostic performance of the GENEDIA Avellino corneal dystrophy (ACD) mutation detection kit and GENEDIA corneal dystrophy screening master mix (Green Cross Medical Science Co., Korea) by comparing it with an in-house sequencing method. METHODS: The study group consisted of 40 patients with Avellino corneal dystrophy (ACD) and 40 patients suspected to suffer from ACD; 40 healthy individuals were used as the control. All samples used for this study were previously obtained. All results obtained using the kit were evaluated for sensitivity, specificity, and detection limit. RESULTS: The sensitivity of the GENEDIA ACD kit was 100.0% with a positive mean+/-2SD Ct (cycle threshold) value of 25.87+/-1.24 and an excellent coefficient of variation value of 0.02 in ACD group. All normal control samples were negative, indicating a specificity of 100% for the GENEDIA kit. The detection limit was set at a DNA concentration of >0.2 ng/microL. Direct sequencing results obtained using the GENEDIA master mix and the in-house method agreed for all 20 ACD samples. Additional R555W mutation detected in four ACD-suspected samples were suggestive of the diagnosis of granular corneal dystrophy type I. CONCLUSIONS: The GENEDIA ACD detection kit and master mix showed acceptable results, demonstrating high sensitivity and specificity, and may be considered for clinical application. Furthermore, the GENEDIA master mix was useful for the detection of mutations in exons 4 and 12 of the TGFBI gene.
